Hey Brett Cardos are disposable . . . you have to buy one every year because they crap out. I was a dealer for them and used one myself (actually three) for almost three years. The first one failed and had to be replaced under warranty. The second fell apart and failed in under a year and even though I was hard on it the quality really wasn't there. I didn't try to warranty, I just bought another one. That one crapped out in about two weeks of use and that one I tried to return. They wanted to replace it and wouldn't just take it back and refund my money - which is what I wanted. I had to push harder than necessary to get my way, which is not right to do - especially to one of your dealers. I let them know I was switching teams and went with Sena, which is what I now use.
IMO Sena is better quality- more durable, good sound, and great customer service. I've been with them a few years and they stand behind their product and send you firmware updates when they happen. I only use mine for my iPhone, others can chime in about the quality with the music or intercom. There is no radio just mp3 capability. And their new model - the 20S - will be out before the end of the month. That one looks nice and has more range.
Anything BUT Cardo!
